Van Buskirk, Southport, Conn,assignor to Van Buskirk & (3a., incorporated, Bridgeport, Conn, acorporation of Connecticut Filed Nov. 2-3, 1955, Ser. No. 624,058 7Claims. ((31. 1611-35) This invention relates to marking or printing onpackages or other articles, and more particularly to apparatus andmethods of employing rotary printing or marking means for marking aseries of similar articles and aotuated in response to movement pastsuch means of the articles to be printed or marked.

It has been known heretofore to provide for the marking of articles orpackages by means of rotary printing drums, and the registration of themark has in some cases been sought to be controlled by normallymaintaining the drum in a predetermined rest position between printingsand causing the same to be picked up and frictionally operated by thearticle to be marked as it is driven past the drum by suitable conveyingmeans. For many purposes this arrangement has proved effective,especially when carried out with appropriate controls, as shown in myprior applications, Serial No. 320,463 filed November 14, 1952, now US.Patent No. 2,834,284, and Serial No. 443,927, filed July 16, 1954, nowUS. Patent No. 2,870,702.

However, there are some situations in which the driving of the printingdrum by contact with the article to be printed does not prove to befully effective. As an example, when it is desired to place printing ata location closely adjacent the leading edge of an article and even moreespecially when it is desired to print substantially the full face ofthe article so that no space is provided for driving contact other thanwith the type surface, the impression is sometimes marred by slippageand the like.

It is accordingly one object of the present invention to provide for themaking of impressions on an article moving past a rotary printing drumin such a way that print ing quality can be maintained regardless of therelative area or placement of the mark.

According to the present invention the foregoing object is achieved byproviding a rotary printing drum having a stationary home position andmeans for driving the drum at a surface speed substantially the same asthat of the article, together with means for initiating action of thedrum at the precise instant necessary to make it reach article speed bythe time that printing contact begins and also to place the mark at thedesired location with a high degree of exactness. In this connection Ihave discovered that an electromagnetic clutch device, tripped by meansactuated by the article to be marked, and making the driving connectionwhich alters the condition of the printing drum from one of immobilityat home position to one of rotary motion at substantially articlesurface speed, has special properties insofar as securing accurateresults are concerned. In many cases it is desired to place a mark inprecise registry with the outline of the article or other preformedindicia on the article, under conditions such that the slightestdeviation from the prescribed position would be clearly noticeable andwould mar the efiect. I have found that with my improved organization,including such article tripped electromagnetic clutch device, theultimate in accuracy of registration can be achieved. In fact, byapplication of the principles of the present invention it has even beenfound possible to test exactness of registration by rerunning andoverprinting an article previously marked on the machine, with resultsof such high quality that the fact of the subsequent running cannot be"ice determined by visual inspection, except possibly by comparison ofcolor density of the mark in some instances.

A feature of the present invention is the provision of means whereby thelocation of the mark along the article in the direction of movement canbe readily and conveniently adjusted to the exact location desiredwithout the necessity for effecting any mechanical change in theequipment.

Another object of the present invention is the provision of an improvedprinting drum having a demountable typecarrying part whereby changeoverof the type between runs can be efieoted in a matter of seconds.

Additional objects, features and advantages will appear hereinafter asthe description proceeds.

In the drawings:

FIG. 2 is a top plan of the device of FIG. 1, but showing the samepositioned relative to a conveyor, an article carried by the conveyor,and a pair of feeler-operated switches associated therewith in acontrolling relation.

FIG. 3 is an axial section of the printing drum shown in FIGS. 1 and 2.

FIG. 4 is a section taken substantially on line 4-4 of FIG. 3.

FIG. 5 is a section taken substantially on line 5--5 of FIG. 3.

FIG. 6 is a schematic view of the printer of the present inventionincluding a wiring diagram.

Referring to the drawing, the present invention is concerned with aprinting head 11 including a frame 13 which rotatably supports aprinting drum 15 which is carried drivingly connected to a shaft 17.Preferably the shaft 17 is rotatably supported in bearing blocks 19which are slidable on the frame 13 and urged to a forward position bysprings 21 to provide a certain amount of resiliency to the drummounting which will allow for unevenness in the surface of the articlebeing marked or slight inaccuracy in the positioning of the frame 13relative to the article path.

The frame 13 is mounted adjacent a conveyor 14 which carries articlespast the same in contact with the printing surface of drum- 15. Forconvenience, the conveyor is illustrated in FIG. 2 as including a pairof guide rails 23 and 25 between which is propelled an article 27 by anysuitable means (not shown). Mounted adjacent the path of the article.27, at any suitable location, are a pair of electrical switches 23 and31 arranged to be closed by a feeler 33 whenever the latter is incontact with an article 27, and whose connections and operation willappear hereinafter as the description proceeds. The drum shaft is shownin FIGS. 1 and 2 in rest or home position. At one end of the shaft is adisk 35 having a notch 37. A locking member 39 occupies this notch 37and locks the drum in home position when appropriate. The locking memberor tongue 39 is operated by a solenoid 41 through a shaft 43 and an arm45 to remove tongue 39 from the notch 37 whenever the solenoid isenergized.

Means are provided for rotating the printing drum and include a sprocket47 on the drum shaft 1'7 driven through a olrain 49 which encircles adriving sprocket S1. The driving sprocket 51 is secured to the drivensection 53b of icountershaft assembly 53 which includes the drivingsection 53a, the driven section 53b, and a connecting electromagneticclutch 53c. The driving section 53a receives its power from \anysuitable source and is continuously rotated thereby at a speedsufiicient to provide the printing drum with a surface speedsubstantially equal to that of :an article being moved by the conveyor14. Two alternative forms of driving the shaft section 53a are bothillustrated in FIG. 1, and while both could be used together as shown,it will be understood that in the normal course of affairs either one orthe other would be employed alone.

One power-supplying device is illustrated as a flexible shaft 55 whichmay be connected to the drive for conveyor 14 at any suitable point (notshown) to take off power at the desired rotary speed indicated above.

The other power-supplying device, and the one presently preferred, isindicated generally by reference numeral 57 and includes an electricmotor 59 driving, through suitable gearing 61, a sprocket 63, a chain65, and a sprocket 67 on countershaft section 53a. The gearing 61 andsprocket sizes are calculated to give a surfiace speed of drum 15 whichis as nearly as possible the exact rated surface speed or an articlebeing moved by the conveyor 14. This speed need not be absolutely exactfor most purposes with printing drums of normal peripheral sizes. It hasbeen found that in most cases the mark is perfect so far as normalvisual inspection is concerned if the speed difference does not exceedabout ten par-ts in one hundred with the conveyor having whatever speedadvantage may exist. In this way it has been found possible to use stockgears and sprockets and still obtain sufliciently similar speeds forexceptional printing quality. It should be pointed out that in thissituation both the conveyor 14 :and the drum 15 will norm-ally beelectrically powered, and that if ample motor size is allotted to eachfunction, and the electric power drawn from about the same supplycircuit location, voltage fluctuations, if any, will affect both partsof the system equally so that adequate mechanical synchronization willbe had under :all supply voltage conditions. With an arrangement asdescribed it is possible to provide for any one machine .a number ofprinting heads which are instantaneously interchangeable, since merelyplugging or unplugging the power cable is .all that is required beyondmanipulation of such fastener as may be used to hold the frame 13 inplace. It will be understood, of course, that any suitable quick-actingreadily releasable hastening means maybe used to secure the frame 13 toa suitable base such as a fixed portion of the frame (not shown) ofconveyor 14.

Attention should be called to the arrangement of countershaft assembly53, printing drum shaft 17 and the connecting driving means 47, 49, 51.It will be seen that by providing the shafts in a parallel arrangementand making the direction of motion of bearing blocks 19 approximatelytangent to a circle centered on the countershafit assembly 53 so thatthe degree of mesh between sprockets 47 and 51 and chain 49 is notsubstantially altered during movement, the printing drum is free to makeslight compensating movements, but its drive can be continuous duringsuch slight movement, and the clutch 530 for making and breaking thedrive connection can be immobile but still accurately control theoperation of the slightly shiftable printing drum.

At the upper end of countersharft portion 53b are cams 69 and 71. Whilethey are shown in this position for construction convenience it will beunderstood that any location providing a rotary speed equal to that ofthe printing drum will serve the purpose. The cam 69 serves to open andclose an electrical switch 73 once each revolution in connection withthe inking function in a manner which will presently appear. The cam 71is shown as having a circular peripheral portion 75 which holds anelectrical switch 77 closed during most of its rotation, but provides alocal deviation corresponding to the home position of drum 15, hereshown as .a notch 79, allowing the switch 77 to open when the drum 15 isin home position. As will presently appear, cam 71 and switch 77 providethe main elements of a mechanically maintained electrical holdingcircuit which assures continued energization of clutch 530 in allpositions of drum 15 except the home position, whereby the drive to thedrum through clutch 53c will be maintained in tall non-home positions,thus always returning the drum to home position regardless of the timeof termination of other drive controlling infiuences thereon.

In FIG. 6 are illustrated in detail some of the parts heretoforedescribed, in relation to the electrical devices and connections whichcontrol the operation. The main alternating current supply consists ofconductors 81 and 83, and it can be seen that the switch 29 controls theenergization of solenoid 41 therefrom by Way of a circuit 35. Arectifier 87 converts the power in supply lines 81, 83 to direct currentfor feeding the electromagnetic clutch 530 by way of a circuit 89.Making and breaking of this circuit is under control of a switch 91 ofthe relay 93, or under control of switch 77 which is in a parallelcircuit '95 bypassing the switch 91.

A controllable precision time delay mechanism 97 is also provided foroperating relay 93. One form of delay mechanism 97 which is generallyillustrated in the drawing and which is presently commercially availableconsists of an electronic time delay mechanism having a manuallysettable control element 99. The delay mechanism draws its power firomthe supply lines 81, 83 via a circuit 101 and provides rectification andvoltage regulation as part of its component parts. A trip circuit 103from the time delay mechanism 97 is connected with feeler switch 31 andwhen the latter is closed it sets in motion the timing operation of themechanism 97 which thereupon, via l3. control circuit 105, energizes therelay 93 after the predetermined time period has elapsed. Althoughillustrated for convenience as .an ordinary solenoid relay, the relay 93is preferably a fast-acting relay tube of a type commercially available,and the relay 9'3 and circuit 105 will normally be (furnished assembledon the same chassis as the time delay device itself. By adjusting themanual control element 99, the time el-apsing between the closing :ofswitch 31iand the closing of switch 91 of relay 3 can be accuratelypredetermined substantially in microsecond increments.

In FIGS. 1 and 2 is generally illustrated an inking mechanism 107including in inking roller 109 making inking contact with the type onthe printing drum 15, a pump 111, and a pump operating solenoid 113. Thesolenoid 113 is in circuit with the switch 73 which peri odicallyenergizes the same. However, inasmuch as the preferred form of theinking mechanism actually shown forms no part of the present invention,reference is had to my copending application, Serial No. 596,329 filedJuly 6, l956,'for a showing of the same in detail.

In operation, articles27 are fed to the printing point in a spacedseries by the conveyor 14. As an article approaches the printing pointit first strikes the feeler 33 thereby closing switches 29 and 31.Closing switch 29 energizes solenoid tl thereby withdrawing tongue 39from notch 37 and unlocking the printing drum 15. Closing of switch 3 1energizes the trip circuit 103 of the delay mechanism 97 so that ashort, accurately measured interval later, as determined by the settingof control element 99, relay 93 is energized, closing its switch 91 andthereby energizing the electromagnetic clutch 53c. Thereuponcountershaft part 53b commences to rotate withthe continuously rotatingcountershaft part 53a'and rotation of the printing drum 15 is initiated.The printing drum is quickly accelerated to article surface speed androlls the printed mark onto the adjacent face of the article as it ismoved along by the conveyor 14.

It will be noted that as soon as the countershaft part 53]) starts torotate, switch 77 is closed by cam'71, so that energization for theclutch 530 is assured regardless of when the switch 91 opens, androtation of the printing drum 15 continues at least until it reacheshome position again. Normally, prior to this time, the marked article 27will have passed beyond the feeler 33 so that solenoid 41 will havebecome deenergized and tongue 39 will have dropped against the uppersurface of locking wheel 35. Furthermore, switch 31 will have beenopened, as will also switch 91 of relay 93, so that when the drum 15finally reaches home position, notch 79 in cam 71 permits switch 77 toopen, thus breaking all circuits to the clutch 530 to stop the drive tothe printing drum. Simultaneously tongue 39 drops into notch 37 to lockthe printing drum precisely in home position to await the initiation ofanother cycle by the next article 27 of the series.

In order to place the mark at the exact location desired along thearticle, it is necessary merely to run through several test articles,making a slight adjustment of the manual control element until thedesired printing position is achieved. Thereafter, so long as thissetting is maintained, and the type on the printing drum remains in thesame location, the mark will be made at exactly the desired point oneach article.

In order to make changeover from one printing job to another extremelyrapid, I have provided an improved printing drum 15 having aninexpensive typecarrying part which can be quickly withdrawn from thebalance of the drum, or as quickly replaced. This avoids actualseparation of the type from the drum and makes it possible to hold thetype in precisely the same location used in making the time delaysetting, so that, if the setting of manual control element 99 isrecorded, it is possible to repeat a printing similar to a previous onewithout running the test articles through, even though other printingswith different settings have intervened.

The improved printing drum 15 is shown in detail in FIGS. 3 to 5 andincludes, pinned to the shaft 17, a toothed wheel 108. A base disk 109'is rotatable and slidable on shaft 17 and rigidly carries an internallytoothed sector 111' which can be moved axially out of mesh with wheel1118 by sliding the disk 109'. The parts can then be reengaged afterrotating them through a certain relative angle. This provides a simplemeans for obtaining the correct angular position of the type on theprinting drum in a fairly precise manner, but its use is not normallycalled for when equipment such as the delay device 97 is employed. Thedrum 15 also includes a head disk 113 slidable on shaft 17 and which maycarry a peripheral tire 114 for driving engagement with the inkingmechanism. The adjacent faces of the head disk 113 and base disk 109have locating and centering means, such as the flanges 115 and 117respectively, between which is carried a removable body elementgenerally designated 119. The body element 119 consists essentially of afairly thick-walled, relatively rigid tube 121 which is slotted from endto end as indicated at 123. The slot 123 is wide enough to pass freelythe shaft 17 during doffing and donning of the body element 119. On theexterior surface of the body element are mounted suitabletype-supporting means, e.-g. a resilient blanket 125 and a resilientcorrugated base 127 for interlocking with resilient type, havingsimilarly corrugated parts, in a known manner.

The base disk 109' also carries a key 129 which is just the width ofslot 123 and serves to fit within the same and thus lock the bodyelement 119 against rotation relative to base dick 169 and shaft 17.

In order to change type using the improved printing drum 15, it isnecessary merely to move the head disk 113' in a direction away from thebase disk 109 and lift the body element 119 free, allowing the shaft 17to pass through slot 123 in the process. Another body element 119 havingdifierent type thereon can then be inserted by reversing the process.When the body element is substantially in place, its slot 123 is fittedto key 129 and the head disk 113 and base disk 109' are brought togetheragainst its ends to center and position the same with respect to shaft17.

While the printing drum parts in the present showing are so arrangedthat the force of gravity retains them in assembled position, it will beunderstood that spring means urging the head disk 113 towards the basedisk 109' can also be employed if desired.

For most purposes a circular tire 114 is preferred for drivingengagement with the inking mechanism, since the frame 13 can ordinarilybe adjusted to a level such that the tire 114 will be above the articlesmarked and will fail to have frictional contact therewith. If, however,it is desired to make a mark at a low point on a series of tallarticles, the inking operation will not be seriously affected, if thehead disk 113 is also made with a flattened side for facing towards theconveyor when the drum is in home position, similar to that shown forthe body element 119.

From the foregoing description it will be seen that I have devised animproved rotary printer adapted to provide clear and accurate marking ofpassing articles regardless of the area thereof to be covered andposition of the mark, together with improved features providing forextremely rapid changeover and adjustment during use.

Variations and modifications may be made within the scope of the claimsand portions of the improvements may be used without others.
